CVE-2025-37919

Local system crash via wrong driver-data lookup

Published May 20, 2025 · Updated May 11, 2026

NULL pointer dereference in the AMD ACP ASoC driver in Linux 6.12 through 6.14.5 allows local users to crash the system. The acp_i2s_set_tdm_slot function obtains chip data from the component device's platform-data slot instead of the parent device's driver data, leaving the pointer NULL when its fields are accessed. Low-privileged local access to a system using the AMD ACP audio path is required; the reported consequence is an availability-only crash.
